The present disclosure discloses a zoom lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens group having refractive power; a second lens group having negative refractive power; a third lens group having refractive power; and a fourth lens group having refractive power. The zoom lens assembly may be continuously zoomed by changing positions of the second lens group and the third lens group along the optical axis. A total effective focal length ft of the zoom lens assembly in a telephoto state, and a total effective focal length fw of the zoom lens assembly in a wide-angle state satisfy: 1.3
